In 1995 a Lennox G26 series gas furnace was installed in my home. This past winter I had a water leak problem coming from within the exhaust flue "Y" trap. This problem was fixed by a local Lennox representative at a cost of $195 US dollars. What surprised me is a new "Y" trap exhaust flue ($95 dollar item) needed to be installed. The new flue trap is a one piece construction, where the older flue was a two half construction. Note: this is were the water leak problem was located..at the seam of the two mating halves! This newly installed flue trap seems to have been "redesigned", due to the water leaking pontential problem???? I am wondering if Lennox would considers this a latent design problem. If so, could I request Lennox to provide this part at no charge, due to their design problem?
